The goal of this is to:

1. Attempt to standardize on some file casing based off what we have done with Display Configurator. I'll get to the dbus part of the codebase in a follow-up PR since I want to move system-specific DBus Services under those systems rather than them being top-level.
2. Introduce clearer namespacing, including moving wlroots-specific code into bd::OutputManager::Wlr namespace. There is still work to be done there on having meta-objects be generalized and expanded on so we can support more protocols, but the intent was to better communicate "this is all wlroots-related" going forwards. Side-benefit is redundant naming of "Wayland[...]" is cleaned up. The prefix was redundant.

Other changes:

1. Tweaked usage of enums since we were relying a fair bit on copying the enum value into other QObjects. I also cleaned up our utils for converting to / from the enum values into toString / fromString in the classes themselves.
2. Updated DBus interfaces & paths from BudgieDaemon to Services, communicate anchors in strings instead of the ints to keep it consistent with how we use it in the configs
